How to Make Blueberry Banana Baked Oatmeal Cups

Follow these straightforward steps to bake a batch of oatmeal cups.

  • Preheat and prepare — Preheat the oven to 350°F (175°C). Grease a standard muffin pan or line it with paper liners.
  • Mash the bananas — In a large bowl, mash 2–3 ripe bananas until smooth.
  • Combine wet ingredients — Add the egg, milk, honey or maple syrup, and vanilla to the mashed bananas and whisk until combined.
  • Add dry ingredients — Stir in the rolled oats, baking powder, cinnamon, and salt until evenly mixed.
  • Fold in blueberries — Gently fold in the blueberries so they stay intact and distribute evenly.
  • Fill the muffin pan — Spoon the batter into the prepared muffin cups, filling each about 3/4 full. Top with a few extra blueberries if desired.
  • Bake — Bake 25–30 minutes, until the tops are golden and a toothpick inserted in the center comes out clean. If using frozen berries, add a few extra minutes.
  • Cool — Let the cups cool in the pan for 5–10 minutes, then transfer to a wire rack to cool completely before storing.
